a child's first bycicle has 12- inch tires. These tires have a 6-inch radious .How far does the bicycle move foward each time the wheel makes one complete rotation?

Respuesta :

Just do 12 * 3.14
Circumference = dynamiter * pi
C=D*P
The diameter is 12 so do
12*Pi the that will equal C

C=37.6

So therefore a child's bicycle takes 37.6 inches to complete its first rotation
